1/2 correct. HP ECU's are already shipping and Dominator's will be ready in a few weeks. Glad to help if anyone has technical questions.

Keith (ForcfdGN) PM'd me this morning with this same info. Keith was adamant that he was not trying to step on anyones toes as I made it clear that I didn't want to waste his time because we are already working with you. Doug at Holley spoke highly of you as well. Like he said, it benefits everyone involved that the product roll out smoothly and that us pioneers be happy. Specially due to the exposure that a high visibility build will bring. I was very happy to hear that the folks at Holley are onboard here as well and are following the threads on the 2 forums. I have a VERY good feeling about this product and if it works half as good as it sounds, it'll be twice as good as anything else out there right now.
Steve (LS2Formula) pulled the BigStuff 3 out yesterday and has started the process of laying out the harness and wiring. By the way, those universal gauges are nothing short of badass! This entire system seems very well laid out and thought threw.
Support so far has been much better than I could have hoped. I was very concerned initially that we were going to be out on island all by ourselves with one coconut tree.

Steve was in the process of pinning out the connector today and getting familiar with the I/O configurator in the software. I'll try to get some interior pictures up with the wiring and some screen shots of what he was dealing with today in the next couple of days. He said he is going to come up with a panel with some inputs and outputs for easy access down the road. This is a street car with full interior though so it's all going to be stashed away behind the dash. The good thing is that in these fbodies, when you get rid of the A/C, airbags and stuff, you can hide 2 adult bodies up in there.

98z28cobrakiller, didn't you also have issues with the BS3 on one of your injector drivers and when you tried to tell Big stuff about it they didn't want to hear it and ended up charging you to fix it when it was their problem because they didn't fix it the first time?

The injector problem was the AEM EMS on BonnarLS1's car. ECM was sending ground to the #3 injector as soon as you put power to it (holding injector wide open). They fixed it and shipped it back no charge. They reluctantly paid freight both ways.

This build will be getting the HP EFI setup. He ordered it yesterday. Steve's Dominator should be here any day now.

since your changing cams...would you mind sharing the specs such as lsa or even the part number of your old one, what rpm did it run to? ...Watching the videos I love the idle ..it didnt seem very lopey,which is what im looking for. Truly enjoyed reading the posts , I know it takes alot of work behind the scenes, but those days at the track are worth it...great job

Dennis (Moore Racecraft) sent us over a base tune. The way that the system works is by using a "global folder" with each part of the tune being a separate file within that folder. So you have a fuel file, spark file, idle file, etc. They all reside within the global folder. When you open up the software, you just open the global folder and it grabs all the files automatically. Just thought that I would mention that as it is different than just one file containing the entire tune as is commonly done.
So we were all set to fire up last night. Flashed the firmware to the latest and greatest, sync'd up the tune to the Dominator. Key On primed the pump for the specified 4 seconds and then started cranking over. Nothing. Motor would just crank and crank. Started checking around and determined that the injectors and the coils were not firing. Also noticed that the pump wouldn't come back on once we started cranking her over. The injectors would get power while the pump was priming but then lost power as soon as we would start cranking.
Called Dennis and he started having us run thru some stuff to check out. First thing that we had to get him was a log so he could see what was going on. Steve's Wnidows 7 laptop could not get the logger working. Went and stole his sons WinXP laptop and set up all the software on it and then we were able to get the log working. Sent the log to Dennis but it was inconclusive as to what was happening besides the voltage dropping into the 9's while cranking over. I'm going to check to see where my voltage on my car goes while cranking over just to see if that's abnormal.
Our biggest concern was that there was an issue with the cam and/or crank signal. He switched to a 58X crank wheel and 4X cam sensor for this go around as it is supposed to be more accurate and the Holley supports it. Putting an external wheel on this thing is NOT an option. Because the coils, injectors and pump are all energized by the same signal to a relay, we figured that we would try to trigger the relay directly. Put 12v to the relay and it fired right up. Once it's running, we could disconnect the direct power and it would stay on. This was a big relief as he wasn't looking forward to having to chase down a relluctor wheel issue which means pulling the motor out and apart.
So that's about as far as we got last night. Push comes to shove, he can hot wire the relay to the key and it will work but it would be nice to know what's causing the issue.

Apparently something in the distribution block for the power was causing the problem and pulling a full extra volt. Steve went straight to the battery with the starter wire and it fires right up. The signal wire now reads 10.8v while cranking and that seems to be enough. Ready to start tuning.

No more tuning until he gets a chance to get the interior back together.

With that wiring deal.. I'd tune it with the dash off in case you need to get at something LOL
I'm just really picky about stuff like that, as long as it makes sense to those involved run with it, you have a good handle on what's going on and that's all that matters.
I'm very intersted in how the system works out. With the way the files are structured, it should be easy to get the car to idle, etc. I'd think. And, it's nice to be able to just touch one portion of the tune by touching just that portion's file.. I like that. Less of a chance of making a change where ya don't really want it.

As for the files being segmented, it's still seamless. In other words, once you have the base global folder put together, you would never know that there are different parts to it. You can still screw up something else by accident.

Got the dash back in. We ran into a problem with the wiring for the fans. Something with the fan relays was causing the computer to freak out. He put the fans on a switch and it's working good now.
Hopefully we can get some tuning in the near future. The only thing that the auto tune thing seems to be struggling with is idle. I know that widebands aren't real accurate at idle and since this thing depends on it to do it's correction, it seems to be over compensating. Now that it's really ready, I'll get the idle sorted out quick as soon as I can get over there. No big deal.

i have just decided to never use any aftermarket system, LMAO! i would loose my mind with something like that!
but kudos to you my friend, lol
looks great! get that beast running!
i do love the ams location
